RADIATO R FOR HEATING-FURNACES.

SPECIFICATION forming part of Letters Patent No. 250,354, dated December6, 1881.

Application filed August 17, 1881.

To all whom it may concern:

Be it known that I, LEWIs W. HEMP,a citizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Radiators forHeating-Furnaces; and I do hereby declare that the following is a full,clear, and exact description of the same, reference beinghad to theaccompanying drawings, forming a part of this specification.

My invention relates to certain improvements in that class of radiatorswhich are used in connection with heating-furnaces; and the objects ofmy improvements are, first, to provide a simple, cheap, and effectiveconstruction of radiator, whereby a more effectual heating of the air isaccomplished without retarding the draft through the same to any greatdegree; second, to afl'ord facilities for regulating and controlling thedraft through the radiator; and, third, to provide a means for readilycleaning the radiator when choked up with soot, &c. I attain theseobjects by the mechanism illustrated in the accompanying drawings, inwhich- Figure 1 is a vertical section of my improved radiator. Fig. 2 isa horizontalsection at line so a), Fig. 1; and Fig. 3 is a detailsection, showing the arrangement of circulating heaterpipes.

As shown in the drawings, this invention consists of aninclosing-casing, A, having an opening, a, communicating with the outletof the furnace B, which furnace may be of any suitable form andconstruction.

Within the radiator-casin g A is arranged a bell-mouthed diaphragm, O,that forms a partition within the chamber, as clearly indicated inFig.1, the object being to direct the currents of heated air, &c.,upward and outwardly, and then downwardly through the opening 0, andbackwardly through the outlet flue or opening D. By this means I amenabled to produce a very efi'ective circulation of the heated productsof combustion within the radiator, and thereby fully realize the propereffect of the -heat from the furnace, and that with but very littleobstruction to the draft.

It is evident that while the passage or open- (No model.)

in g c is shown as diametrically opposite the outlet-opening D, yet theposition of the said opening may be varied (by turning the diaphragm) soas to suit the draft of the chimney to which the invention is applied.With a good draft it can belocated directly opposite the outlet-openingD, while with a poor draft it can be changed relatively nearer to the ontlet-opening.

E represents a series of heating-pipes passin g from the bottom to theside of the radiator, as clearly indicated in Fig. 3, the purpose ofwhich is to form a circulating-heater for the air that is used inheating the building, and which is contained within the casing of thefurnace.

F is an opening or hand-hole formed in th side of the radiator for thepurpose of removing any accumulation of soot, &c., from the interior ofthe same.

G G are partitions arranged before the outlet-flue D, as shown, andprovided, one or both, with a damper, g, by which the draft can beregulated and guided to one or the other side of the radiator.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. Aradiatorforheatingfurnaces, consisting of a casing, A, bell-shapedpartition or diaphragm 0, opening 0, and inlet and outlet openings at D,as described, and for the purpose set forth.

2. Aradiator for heating-furnaces, consisting of a casin g,A,bell-shaped partition 0, opening 0, partitions G Gr, damper g, andinlet and outlet openings on D, as herein described, and for the purposeset forth.

3. Aradiatorforheating-furnaces,consisting of a casing,A,bell-shapedpartition G,opening c, and heating-tubes E, as described, and for thepurpose set forth.

In testimony whereof I have hereunto set my hand, at St. Louis,Missouri, this 13th day of August, 1881.
